NASA, Boeing Provide Update on First Crewed Starliner Flight Test

The Boeing CST-100 Starliner spacecraft was moved into the Hazardous Processing Area at the company’s Commercial Crew and Cargo Processing Facility at NASA’s Kennedy Space Center in Florida on Feb. 8, 2023, in advance of power up and fueling operations. NASA’s Boeing Crew Flight Test will demonstrate the end-to-end capabilities of the Starliner system to carry astronaut to and from the International Space Station.

NASA and Boeing held a mission overview media teleconference Friday to provide a status update on the first astronaut flight test of the company’s CST-100 Starliner to the International Space Station.

During the call, managers shared mission progress and discussed upcoming milestones ahead of NASA’s Boeing Crew Flight Test (CFT), which is targeted to launch no earlier than mid-to-late April to the microgravity laboratory.

A replay of the teleconference is available on NASA’s YouTube channel.

CFT is the final flight test prior to regular crewed missions to the space station on the next-generation system. For CFT, the Starliner spacecraft will launch on a United Launch Alliance Atlas V rocket from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida, returning approximately eight days later in White Sands, New Mexico. The flight will carry two NASA astronaut test pilots, Barry “Butch” Wilmore and Suni Williams, on the demonstration flight to prove the end-to-end capabilities of the Starliner system.

Following a successful test flight with astronauts, NASA will begin the final process of certifying the Starliner spacecraft and systems for regular crew rotation flights to the space station.

NASA, Boeing Teams Achieve Milestone Ahead of Crewed Flight

NASA and Boeing recently completed a full start to finish integrated mission dress rehearsal for the company’s CST-100 Starliner flight with astronauts to the International Space Station, which is scheduled to launch in April 2023.

The Crew Flight Test, or CFT, will launch NASA astronauts Barry “Butch” Wilmore and Suni Williams on Starliner – atop a United Launch Alliance Atlas V rocket – from Space Launch Complex-41 at Cape Canaveral Space Force Station as part of the agency’s Commercial Crew Program.

During several days at Boeing’s Avionics and Software Integration Lab (ASIL) in Houston, the ASIL Mission Rehearsal (AMR) combined tests of software and crew systems, along with operations teams. The completion of the end-to-end mission rehearsal clears a path for the next CFT milestones, including working with the crew and flight controllers on various integrated failure scenarios and a series of flight-day parameter updates that will become available as the team nears launch day.

“Testing is a key component to the success of a human space program,” said NASA Commercial Crew Program Software Certification Manager Chad Schaeffer. “The AMR and the integrated failure scenarios are excellent examples of the rigorous testing teams are performing on Starliner. The rehearsal went well and reflects the continued improvement in executing this test and helps pave the way to the much anticipated first crewed flight.”

During the rehearsal, Wilmore and Williams, along with fellow NASA astronaut Mike Fincke, worked through mission milestones in coordination with mission operations teams located inside flight control rooms at NASA’s Johnson Space Center. Starliner engineering teammates also supported from Boeing’s Mission Control Center located in Florida.

The crew members worked in a flight deck simulator networked to control rooms and avionics, operating the same software that will be used during CFT. They effectively demonstrated the software is ready to operate Starliner during prelaunch, launch, docking to the space station, undocking, and the return to Earth through landing.

The AMR provided end-to-end testing of hardware configuration, software, communications, preparation configuring hardware and software, routing communications channels, and mapping simulated sensor data. Similar testing was performed ahead of NASA and Boeing’s Orbital Flight Test-2 (OFT-2) uncrewed mission in early 2022.

“We began conducting AMRs with the creation of OFT-2, and the integrated team has continued to get more efficient with each rehearsal,” said Aaron Kraftcheck, Starliner avionics software integration and test manager. “With the participation of our astronauts in this CFT AMR, we have enhanced the team dynamics, and continued to learn and adjust, which is what AMR is all about.”

NASA will fly two astronaut test pilots aboard the agency’s Boeing Crew Flight Test (CFT) mission to the International Space Station, where they will live and work off the Earth for about two weeks.

CFT commander Barry “Butch” Wilmore, whom NASA assigned to the prime crew in October 2020, will join NASA astronaut Suni Williams, who will serve as pilot. Williams previously served as the backup test pilot for CFT while assigned as commander of NASA’s Boeing Starliner-1 mission, Starliner’s first post-certification mission. As CFT pilot, Williams takes the place of NASA astronaut Nicole Mann, originally assigned to the mission in 2018. NASA reassigned Mann to the agency’s SpaceX Crew-5 mission in 2021.

NASA astronaut Mike Fincke, whom the agency previously assigned as the Joint Operations Commander for CFT, will now train as the backup spacecraft test pilot and remains eligible for assignment to a future mission. Fincke’s unique expertise will continue to benefit the team as he retains his position as flight test lead, filling a vital role in Starliner certification.

Boeing’s CST-100 Starliner spacecraft completed its touchdown at 6:49 p.m. Wednesday, May 25, at White Sands Space Harbor in New Mexico, wrapping up the uncrewed Orbital Flight Test-2 as part of NASA’s Commercial Crew Program.

Starliner settled gently onto its air bags following a parachute-assisted landing that helps set the stage for future crewed landings. The landing followed a deorbit burn at 6:05 p.m., separation of the spacecraft’s service module, and successful deployment of its three main parachutes and six airbags.

NASA and Boeing will host a postlanding news conference at 9 p.m. on NASA TV from NASA’s Johnson Space Center in Houston with:

  • Steve Stich, manager, NASA’s Commercial Crew Program
  • Joel Montalbano, manager, NASA’s International Space Station Program
  • Suni Williams, NASA astronaut
  • Mark Nappi, vice president and program manager, Boeing

Starliner launched on a United Launch Alliance Atlas V rocket on a flight test to the International Space Station at 6:54 p.m. on Thursday, May 19, from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. The uncrewed spacecraft successfully docked to the space station’s Harmony module at 8:28 p.m. Friday, May 20.

NASA Television, the NASA app, and the agency’s website continue to provide live coverage of the landing of Boeing’s CST-100 Starliner spacecraft.

At 6:05 p.m. EDT, the spacecraft began its deorbit burn that puts Starliner on the right path to land at 6:49 p.m. White Sands Space Harbor in New Mexico. The service module has successfully separated from the crew module containing Rosie the rocketeer, an anthropometric test device who will help maintain Starliner’s center of gravity from ascent through landing. During OFT-1, Rosie was outfitted with 15 sensors to collect data on what astronauts will experience during flights on Starliner.

At 6:44 p.m. the drogue parachute will be released, pulling out the spacecraft’s three main parachutes at 6:45 p.m. that will slow the capsule to a safe landing on Earth.

Booster ignition and liftoff of the United Launch Alliance Atlas V rocket carrying Boeing’s CST-100 Starliner spacecraft on NASA’s Orbital Flight Test-2 to the International Space Station. Launch occurred at 6:54 p.m. EDT from Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida.

About one minute after launch, the Atlas V rocket achieved Mach 1. About two-and-a-half minutes into flight, a series of key events will begin to occur over the next few minutes. The Atlas V solid rocket boosters will fall away. The Atlas first-stage booster engine will cut off, followed by separation from the dual-engine Centaur second stage. The Centaur first main engine will start, followed by aeroskirt jettison. A few minutes later the Centaur engine will cut off.
